Description

Technical Field

[0001] This utility model relates to the field of gantry CNC boring and milling machine technology, specifically a sandwich-type gantry CNC boring and milling machine. Background Technology

[0002] A CNC boring and milling machine is a CNC machine tool capable of boring and milling. It features high precision, high rigidity, and high stability. It mainly consists of a boring and milling spindle, tool magazine, feed system, and control system. CNC boring and milling machines are primarily used for machining high-precision holes or completing the finishing of multiple holes in a single positioning operation. In addition, they can perform machining of other surfaces related to hole finishing. Using different tools and accessories, they can also perform drilling, milling, thread cutting, and machining of external diameters and end faces. CNC boring and milling machines typically have a relatively traditional machine tool structure. The design of traditional gantry multi-directional CNC boring and milling machines has significant limitations, mainly in that the boring and milling head is only located on one side and equipped with only a single-sided guide rail. This structure exhibits significant instability and vibration when facing heavy-load machining tasks or when the boring and milling rod extends for a long distance. This not only severely restricts the guarantee of machining accuracy for large workpieces but also greatly reduces machining efficiency and increases the risk of equipment damage. Therefore, performance optimization and structural improvement of such equipment are particularly urgent and necessary. For example, the utility model CN203109593U describes a sandwich-type gantry CNC boring and milling machine with a compact design, reliable performance, stable operation, and long service life. It can complete multi-faceted machining of workpieces in one clamping and is very effective in improving the machining accuracy and efficiency of large parts. While existing technologies may already have solutions to the above problems, this application aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a sandwich-type gantry CNC boring and milling machine, comprising: a bed base, a covering operation frame and a top drive chamber, wherein the covering operation frame is installed on the bed base, the top drive chamber is installed on the covering operation frame, and a sandwich multi-dimensional boring and milling structure is installed inside the covering operation frame;

[0004] The sandwich multidimensional boring and milling structure includes: a top drive motor, a top threaded rod, a top displacement module, a top telescopic air rod, a telescopic connection module, a top punch boring and milling drill bit, a bottom drive motor, a bottom transmission shaft, a transfer gearbox, a pair of opposing screws, and a pair of transverse drive modules;

[0005] The top drive motor is installed in the top drive chamber. The top threaded rod is inserted into the covering operation frame and connected to the top drive motor. The top displacement module is mounted on the top threaded rod and connected to the top telescopic air rod. The telescopic connection module is connected to the top telescopic air rod. The top punch boring and milling drill bit is installed on the telescopic connection module. The bottom drive motor is installed in the bed base and connected to the bottom transmission shaft. The transfer gearbox is installed in the covering operation frame and connected to the bottom transmission shaft. A pair of opposing screws are respectively inserted into the transfer gearbox and respectively inserted into a pair of transverse drive modules. Opposite synchronous adjustment boring and milling components are respectively installed on the pair of transverse drive modules.

[0006] It should be noted that, as described above, the operation panel on the covered operating frame controls the bottom drive motor inside the bed base, thereby driving the bottom transmission shaft, the transfer gearbox, and a pair of opposing screws. This causes a pair of transverse drive modules to slide closer to each other via slide rails on the transverse drive modules, which in turn causes a pair of opposite synchronously adjusting boring and milling components to move closer to each other and fit against the side wall of the workpiece. Then, the top drive motor in the top drive chamber on the covered operating frame is driven to rotate, causing the top threaded rod to rotate and move the top displacement module to the appropriate position. After that, the top telescopic air rod is driven to extend, pushing the telescopic connecting module and the top punch boring and milling drill bit on it closer to the workpiece. This allows the top punch boring and milling drill bit to perform boring and milling on the fitted workpiece. The fine-adjustment electric slide table at the connection of the top punch boring and milling drill bit allows the top punch boring and milling drill bit to be finely adjusted in position, making the boring and milling process more precise and efficient.

[0007] Preferably, the contralateral synchronous adjustment boring and milling assembly includes: a longitudinal displacement push rod, a longitudinal support slider, and a lateral boring and milling drill bit;

[0008] The longitudinal displacement push rod is mounted on the transverse drive module, and the longitudinal displacement push rod is connected to the longitudinal support slider, which is inserted into the transverse drive module.

[0009] It should be noted that, as described above, when a pair of transverse drive modules are displaced to the appropriate position, they drive a pair of longitudinal displacement push rods to extend and retract, thereby causing a pair of longitudinal support sliders to slide within a pair of transverse drive modules until they reach the appropriate machining position. After that, a pair of side boring and milling drills can accurately bore and mill the workpiece. The shock absorber installed at the bottom of the bed base can make the bed more stable during operation.

[0010] Preferably, a shock absorber is provided at the bottom of the bed base;

[0011] Preferably, the covering operation frame is provided with an operation panel;

[0012] Preferably, a fine-adjustment electric slide is provided at the connection of the top punch boring and milling drill bit;

[0013] Preferably, the lateral drive module is provided with a slide rail. Beneficial effects

[0014] This utility model provides a sandwich-type gantry CNC boring and milling machine. It offers the following advantages compared to existing technologies: This sandwich-type gantry CNC boring and milling machine cleverly utilizes a sandwich multi-dimensional boring and milling structure, enabling simultaneous boring and milling of the workpiece from above and from both sides. This design significantly improves the stability and efficiency of the machining process. Compared to traditional single-side boring and milling methods, this machine is more stable and efficient during operation. Furthermore, its equipped side synchronous adjustment boring and milling assembly can flexibly adjust the relative height of the side boring and milling drill bits, thereby greatly expanding the applicable range of machining and significantly improving machining efficiency. This design not only meets diverse machining needs but also further enhances overall production efficiency. Attached Figure Description

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0020] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-2 As shown, a sandwich-type gantry CNC boring and milling machine includes: a bed base 1, a covered operating frame 2, and a top drive chamber 3. The covered operating frame 2 is mounted on the bed base 1, and the top drive chamber 3 is mounted on the covered operating frame 2. A sandwich multi-dimensional boring and milling structure is installed inside the covered operating frame 2. The sandwich multi-dimensional boring and milling structure includes: a top drive motor 4, a top threaded rod 5, a top displacement module 6, a top telescopic air rod 7, a telescopic connection module 8, a top punch boring and milling drill bit 9, and a bottom... The system comprises a drive motor 10, a bottom transmission shaft 11, a transfer gearbox 12, a pair of opposing screws 13, and a pair of transverse drive modules 14. The top drive motor 4 is installed in the top drive chamber 3. The top threaded rod 5 is inserted into the covering operating frame 2 and connected to the top drive motor 4. The top displacement module 6 is mounted on the top threaded rod 5 and connected to the top telescopic air rod 7. The telescopic connection module 8 is connected to the top telescopic air rod 7. The top punch boring and milling drill bit 9 is installed on the telescopic connection module 8. The bottom drive motor 10 is installed in the bed base 1 and connected to the bottom transmission shaft 11. The transfer gearbox 12 is installed in the covering operating frame 2 and connected to the bottom transmission shaft 11. A pair of opposing screws 13 are respectively inserted into the transfer gearbox 12, and a pair of opposing screws 14 are connected to the bottom drive shaft 11. 3 are respectively inserted into a pair of the transverse drive modules 14, and a counter-side synchronous adjustment boring and milling assembly is respectively installed on the pair of transverse drive modules 14; the counter-side synchronous adjustment boring and milling assembly includes: a longitudinal displacement push rod 15, a longitudinal support slider 16, and a side boring and milling drill bit 17; the longitudinal displacement push rod 15 is installed on the transverse drive module 14, and the longitudinal displacement push rod 15 is connected to the longitudinal support slider 16, and the longitudinal support slider 16 is inserted into the transverse drive module 14.

[0021] According to the appendix Figure 1-2It is found that by operating the control panel on the operating frame 2, the bottom drive motor 10 in the bed base 1 is operated, thereby driving the bottom transmission shaft 11, the distribution gearbox 12, and a pair of opposing screws 13 to rotate. This causes a pair of transverse drive modules 14 to slide closer to each other via the slide rails on the transverse drive modules 14, thereby causing a pair of opposite synchronous adjustment boring and milling components to move closer to each other and fit against the side wall of the workpiece. Then, the top drive motor 4 in the top drive chamber 3 on the operating frame 2 is driven to rotate, thereby causing the top threaded rod 5 to rotate, which in turn causes the top displacement module 6 to rotate and move to the appropriate position. Then, the top telescopic air rod 7 is driven to extend, thereby pushing the telescopic connection module 8 and its upper part. The top-punch boring and milling drill bit 9 is brought close to the workpiece, allowing it to perform boring and milling operations on the workpiece. The fine-tuning electric slide table at the joint of the top-punch boring and milling drill bit 9 allows for appropriate fine-tuning of its position, making the boring and milling operation more precise and efficient. When a pair of transverse drive modules 14 are moved to the appropriate position, they drive a pair of longitudinal displacement push rods 15 to extend and retract, thereby causing a pair of longitudinal support sliders 16 to slide within the pair of transverse drive modules 14 until they reach the appropriate machining position. Then, a pair of side boring and milling drill bits 17 can accurately perform boring and milling operations on the workpiece. The shock absorber at the bottom of the bed base 1 makes the operation of the bed more stable.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
